 Three log surfaces, in order of usefulness:
 
-- **Donut Browser GUI** — `~/Library/Logs/com.donutbrowser/DonutBrowser.log` on macOS (newest = active session; older `DonutBrowser_<date>.log` are rotated). The GUI / Tauri / `browser_runner` / `proxy_manager` / `sync` all log here. Search for `Camoufox`, `Wayfern`, `Starting local proxy`, `Configured local proxy` to find a launch chain.

Dev builds write to `DonutBrowserDev.log` instead.
 - **donut-proxy worker** — `$TMPDIR/donut-proxy-<config_id>.log`. One file per proxy worker process (each profile launch spawns a fresh one). Map a worker to its launch via the `Cleanup: browser PID X is dead, stopping proxy worker <id>` lines in DonutBrowser.log, or by mtime. CONNECT requests, upstream accept/reject (status lines like `HTTP/1.1 402 user reached limit`), and tunnel errors are at INFO/WARN — anything finer is at TRACE and requires `RUST_LOG=donut_proxy=trace`. The `Upstream CONNECT response coalesced N byte(s) of payload — these would be dropped without forwarding` warning marks a real bug in `handle_connect_from_buffer` if it ever fires.
-- **Camoufox stderr** — `$TMPDIR/camoufox-stderr-<profile_id>.log`, written by `camoufox_manager::launch_camoufox`. Captures NSS / GPU Helper / juggler errors. Firefox does **not** print TLS/network errors here by default — set `MOZ_LOG=nsHttp:5,signaling:5` on the env if you need that. The `RustSearch.sys.mjs missing field 'recordType'` lines are noise from our `search.json.mozlz4` schema being slightly off for FF150+; not a network problem.

 - Never write user-facing strings as raw English literals in JSX, toast messages, dialog titles/descriptions, button labels, placeholders, table headers, tooltips, or empty-state text. Always go through `t("namespace.key")` from `useTranslation()`.
 - This applies to every component under `src/` — including new ones. If a component doesn't already import `useTranslation`, add it.
-- Adding a new string means adding the key to ALL seven locale files in `src/i18n/locales/` (en, es, fr, ja, pt, ru, zh) — not just `en.json`. The English version alone is incomplete work.
+- Adding a new string means adding the key to ALL nine locale files in `src/i18n/locales/` (en, es, fr, ja, ko, pt, ru, vi, zh) — not just `en.json`. The English version alone is incomplete work.
 - Reuse existing keys (`common.buttons.*`, `common.labels.*`, `createProfile.*`, etc.) before creating new namespaces. Check `en.json` first.
 - Strings excluded from this rule: `console.log/warn/error`, dev-only debug labels, internal IDs, CSS class names, type names. If unsure whether a string renders to the user, assume it does and translate it.
 - **Never use `t(key, "fallback")` with a default-value second argument.** The 2-arg form is forbidden — every key must exist in every locale file before the call site lands. Fallbacks mask missing translations: a key missing from `ru.json` will silently render the English fallback to Russian users, so the bug never surfaces in CI or review. Only call `t("namespace.key")`. If a translation is missing for any locale, that's a bug to fix at the JSON, not a hole to paper over at the call site.
 - Empty-string values in non-English locales are also forbidden — a locale either has the right translation or it has the same content as English; never `""`. If a particular language doesn't need a particular phrase (e.g. a suffix that doesn't grammatically apply), refactor the JSX to use a single interpolated key (`t("foo.bar", { name })` with `"...{{name}}..."` in each locale) instead of splitting prefix/suffix.
-- When adding or removing keys across all seven locales, use a one-shot Python script in `/tmp/` that loads each `*.json`, mutates it, and writes it back. Seven sequential `Edit` calls drift (typos, ordering differences) and burn tokens; a single script keeps the locales in lockstep and is easy to throw away.
